Hi, I've tried to find some answers to this by searching the list archives and Google, but haven't been able to find anything matching my circumstances. Hopefully someone here can help me figure this out, or point me in the right direction for me to solve it myself. I've recently switched my server over to using mpm_worker rather than mpm_prefork, and I'm having problems with much reduced information in the error logs. Whereas before I might see something like this: [Wed Feb 17 10:58:37 2010] [error] [client 114.198.145.132] [pid 23028] main: filename = support_menu.pl I now only see: [pid 1254] main: filename = support_menu.pl In addition, it seems that any ErrorLog entries in my vhosts are ignored, and only the main ErrorLog entry is used. I am running Apache 2.2.14 (patched with CVE-2009-3555-2.2.patch), built with the following configure options: "./configure" \ "--prefix=/usr/local/apache" \ "--disable-userdir" \ "--enable-rewrite" \ "--enable-so" \ "--enable-info" \ "--enable-status" \ "--enable-ssl" \ "--enable-cgi" \ "--enable-unique-id" \ "--enable-mime-magic" \ "--with-included-apr" \ "--with-mpm=worker" \ "$@" I have modsecurity on this Apache installation also, however I've tried disabling it and still see the same behaviour. Upon switching back to mpm_prefork, logs act as I've come to expect in the past. I haven't seen any notes about a difference in logging behaviour between prefork and worker, but maybe I've not dug deep enough? The OS platform is Debian 4.0 if that's relevant, and the prefork and worker sections of the httpd.conf are pretty much the defaults: # prefork MPM <IfModule mpm_prefork_module> ServerLimit 1000 StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 250 MaxRequestsPerChild 0 </IfModule> # worker MPM <IfModule mpm_worker_module> StartServers 10 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 0 </IfModule> Definitely appreciate any advice anyone can give. Again, this only seems to happen when switching from prefork to worker, disabling modsecurity, switching back to Apache 2.2.13 don't seem to have any effect.
